- Question 9 Fill in the data table below with the volume of each of the nuggets that Emilio measured. Nugget Initial Volume of Water Volume after the Nugget is added Volume of Nugget Nugget #1 20.0 mL 22.9 mL Nugget #2 20.0 mL 24.6 mL Nugget #3 20.0 mL 22.3 mL Nugget #4 20.0 mL 26.2 mL Question 10 The density of gold is 19.3 g/mL. Emilio knows he must also measure the mass of each nugget to calculate the density. He realizes that the scale he has only measures in ounces. He will need to convert each of the oz measurements to grams for comparison. (1 ounce = 28.3495 g). Fill in the table below with the converted values for each mass. Nugget Nugget #1 Nugget #2 Nugget #3 Nugget #4 Mass in ounces Mass in grams 1.972 3.126 1.575 4.195Convert the decimal number 426 in binary (base 2) NumberUse the graph and please answer question 12
- A stainless steel cylinder stands 0.08314 m and has a radius of 1.25 cm. Calculate the volume in: a) Cubic meter b) litersAccording to a survey, 85% of American adults eat salad at least once a week. A nutritionist suspects that the percentage is higher than this. She conducts a survey of 200 American adults and finds that 171 of them eat salad at least once a week. Conduct the appropriate test that addresses the nutritionist's suspicion. Use an a = 0.05 level of significance. State the null and alternative hypothesis: What parameter are we testing? Ho: H₁: Assumptions: SRS, n < 0.05N, npo (1 - po) By hand, test statistic is (Round to 5 decimals): P-value. Round to 4 decimals: Conclusion: There is (enter sufficient or insufficient) evidence at the a = 0.05 level of significance to conclude that the percentage of adult Americans that eat salad at least once a week is ("equal to" or "higher than" or "less than" or "not equal to") 85%.A generation is about one-third of a lifetime.

- The world population in billions is approximately P = 7.4e0.010" where t is in years since 2016. Estimate the relative rate of change of population in 2020 using this model and the values of At below. Round your answers to three decimal places. (a) At = 1 The relative rate of change is % per year. the absolute tolerance is +/-0.001 (b) At = 0.1 The relative rate of change is % per year. (c) At = 0.01 The relative rate of change is % per year.How does density differ from mass? Mass decreases as density increases. Density is the mass of an object. Density is a per-volume metric of mass. Mass is a per-volume metric of density.Suppose two variables are inversely related and graphing the dependent variable versus the independent variable gives a straight line. Does the line have a negative or a positive slope? Explain your answer.
